Oh damn, i must admit i am struggling with this, i realise for a rank novice this is a tall order and a learning
curve, but i cannot afford the £100 plus price for the commercial version for my project.
i will have a go at the circuit with my breadboard still stuck with the transistor in the diagram, i do really
appreciate the feedback and comments given, i am happy to consider any alternative including different
power DC voltages (nice to keep easy ie AAA's or AA's or 9 v PP3 etc)
am also happy to consider low voltage relays (reed switch i believe at work so cannot get access to my
paperwork at present)
